Antarctic Circle

At 55 degrees latitude south, Ushuaia (pronounced oo-swy-ah) is closer to the South Pole than to Argentina's northern border with Bolivia. It is the capital and tourism base for Tierra del Fuego, the island at the southernmost tip of Argentina. The city rightly (if perhaps too loudly) promotes itself as the southernmost city in the world (Puerto Williams, a few miles south on the Chilean side of the Beagle Channel, is a small town).

Ushuaia feels like a frontier boomtown at heart, but exhibiting the frayed edges of a city that quadrupled in size in the '70s and '80s and just keeps growing. The weather-worn pastel colors that dominate the town's landscape remind you that Ushuaia was once just a tiny fishing village, snuggled at the end of the Earth. As you stand on the banks of the Canal Beagle (Beagle Channel) near Ushuaia, the spirit of the farthest corner of the world takes hold. Above the city rise the last mountains of the Andean Cordillera, and just south and west of Ushuaia they finally vanish into the often-stormy sea. Nature is the principal attraction here, with trekking, fishing, horseback riding, wildlife spotting, and sailing among the most rewarding activities, especially in the Parque Nacional Tierra del Fuego (Tierra del Fuego National Park).

Sailing the legendary Drake Passage is an experience that few are ever lucky enough to experience. The southern tip of the Americas already feels like a wild enough environment – but the sensation of watching the distant cliffs of the peninsula known as the ‘End of the World’ fade into the horizon, is one that’s equal parts epic, eerie and magical. Set sail to slowly drop off the bottom of the map from Cape Horn, and voyage on an expedition down into the icy underworld of Antarctica. Drake Passage is an extraordinary voyage of romantic ocean faring legend, as you aim for Antarctica’s icy realm. On arrival, skyscraper sized icebergs salute you, as you traverse the waters of this continent where snow and ice dwelling creatures like penguins and whales roam undisturbed. Your first sight of this most-unexplored place will most likely be the South Shetland Islands.

Walk in the footsteps of some of history’s greatest and bravest explorers as you explore famed, snow-covered landmasses like Elephant and Deception Island. If the journey across Drake Passage sounds daunting, don’t worry – even in rough seas you’re never alone, and will often be accompanied on this spine-tingling adventure by soaring albatrosses and maybe even a protective pod of humpbacks and hourglass dolphins or two. Converging warm and cool ocean currents attract some spectacular animal life to the passage.

The ice-coated Antarctic Peninsula forms perhaps the most accessible region of mainland Antarctica, lying a mere 480-miles away from South America, across the fabled waters of the Drake Passage. Lying close to the northwestern tip of the Antarctic Peninsula, separated by the Bransfield Strait, the South Shetland Islands fall under the jurisdiction of the Antarctic Treaty, suspending claims on their sovereignty. Several countries maintain research bases here, and with plump elephant seals, and crowds of Gentoo, Chinstrap and Adelie Penguins also calling the islands home, it can even feel a little crowded at times. King George Island is the largest and most hospitable island, hosting the majority of the research stations - some of which are populated all-year-round by tiny, hardy crews. Don’t be fooled though, these islands offer extraordinary adventure in one of the most remote locations on earth. The triple peaks of Mount Foster tower above the archipelago, and you’ll feel your heart pumping a little quicker, as you sail into the core of Deception Island’s magnificent collapsed volcano caldera. Hike the luna landscapes within, and even dip into the improbably warm, geothermally-heated waters of Pendulum Cove. Elephant Island, meanwhile, is written deep into the annals of Antarctic expedition legend, as the site where Ernest Shackleton and the stricken crew of the Endurance miraculously survived a harsh Antarctic winter, in 1916.

The Antarctic Peninsula unravels upwards towards South America, reaching out a beckoning finger to the adventurous, who dare to explore this untamed realm. Stretching up from the heart of the world’s southernmost continent, the Antarctic Peninsula lies a mere 620 mile from Tierra del Fuego and, for many, offers a spectacular first taste of the snow-blanketed landscapes and colossal ice sculptures which make up Earth’s least-explored continent. Unseen by humans until 1820 - a blink of an eye ago in relative terms - this is an adventure sure to make your hairs stand on end, as you experience the thrill of the truly unknown and extraordinary. The vast peninsula is sprinkled with research bases, which are at the frontline of human scientific endeavor, pushing to study and understand this unique landscape, its exceptional wildlife, and the impact that humans are having on this pristine continent. Witness cathedral-sized icebergs up close, and blue-hued glaciers, slowly slipping from imposing locations like Hope Bay. Blanched mountain peaks cover the peninsula, and you’ll find thousands of adorable Adelie penguin pairs thriving undisturbed in this peninsula’s unique setting.
